WS-Resource Framework WS-Resource Framework ReviewReview

1. Please consider as the additional WS platform technologies that we require:

– Stateful Resource handling– Addressing– Properties– Notification

2. Specification Review– Stateful services and the Implied Resource Model – Specification review –

• WS-Addressing, • WS-Notification, • WS-Resource Properties

3. Q and A4. Discussion on relevance to WSDM Specifications - All5. Vote on how to leverage in WSDM Specifications - All6. WSDM Platform resolutions - outstanding issues, path for resolution

• MetaData

MUWS Spec OutlineMUWS Spec Outline• 1. Meta Model• 2. Architecture – extensive in sep doc; brief in this doc; manager motivation, expose

mgbility ifc about resource• 3. WS Platform Requirements • identify platform functionality required, which specs should be used, the interim

solution if there are not existing specs, or pointer to future• bubbles on chart1• i.e. ID, version, notification, collection, relationship, registry, policy , security,

addressing, etc.• 4. Manageability • identify functionality/capabilities required to support describing and using

manageability of resources using Web services• bubbles on chart2 + • i.e. Resource state model, event format, configuration, metrics, operations,

identity, version, change control, basic relationships for manageability• 5. Discovery and Introspection• finding manageable resources• introspecting manageability interfaces • 6. Defining a manageability interface for a manageable resource using this specification • how to mix in functions in section 3 and 4 – probably normative• profiles of manageable resources? ( configurable? monitorable? ) not sure if

normative• how to satisfy some of the main usage scenarios? – sep doc• Appendix for full schemas, namespaces, types

3. WS Platform Requirements 3. WS Platform Requirements SectionSection

Identify platform functionality required (in addition to WS-I basic profile), which specs should be used, the interim solution if there are not existing specs, or pointer to future

• Identification – Unique Id for svcs• Version – version of service, in URIs today, w3c tab? sufficient?• Attributes • Metadata• Addressing – like ws-addressing and gsr/gsh• Security - +bootstrap security mode?• Flow• Policy – may not be reqd for vers 1• Negotiation• Notification Mechanism• Registration/discovery• Collection• Name Resolution• Relation• Relationship Service?• Logging• Policy Decision Point/Policy Enforcement Point• Lifecycle Support

• WSDL Representation– Properties– Specific Access Operations?

MUWS StateMUWS State• Review Draft

– 3 States standard – Available, Unavailable, Semi-Available– Substates to V1– Operations:

• Get State• Get State Model• Enable• Disable • Control Events

• WSDL Mapping– State model– State transitions– State events– Operations affecting state– Operations - required state– Properties - required state

MUWS - MetricsMUWS - Metrics

• Things to think about1. Metric Organization – sets?2. Metric Metadata – Units, …?3. Metric Events – Metric change? Reset

5. Discovery and Introspection5. Discovery and Introspection

1. finding manageable resources

2. introspecting manageability capabilities

Do we need this for V0.5?
